Jim CarreyWhen I was a stand-up comedian, in the late 80s, I used to open for Jim Carrey on the road. I would do my lame act, and then he would come on and do the most energetic, inventive, uproarious set I had ever witnessed. I retired from performing as a result. He was and is the funniest man on earth. This is something we can all agree on. We can debate No. 2 forever, but Jim will always be the king.
